This was also a fascinating comment. The accusation of "blood libel" -- the use of a child's blood for the making of Passover matzoh -- is an insult to the complex history of the blood libel itself.
Additionally, the history of Ukraine includes National Socialists' allies, per the basic resource on the OUN parties, per WIKI.

I have posted the WIKI resource to other threads, and been told that the partisans of one side in the Ukraine-Russia was don't care.
Lastly, the assertion that Zelensky is Jewish is as valid as those who like to claim that Karl Marx was Jewish because fore-bearers were. Karl Marx was anti-Jewish, as many sources can prove. Zelensky married a Christian woman, and there is no current evidence that he 1) supports a local Jewish congregation, 2) attends, 3) studied Torah, or anything of the sort.
So wrapped into a single attack aimed at you were empty assertions, misuse of historical and religious terms, and a slur. This is what seems to pass today for partisan cheer-leading in the Russia-Ukraine war, a conflict officially between two non-NATO nations and having nothing at all to do with the Jewish population of either Ukraine or Russia. "Blood libel" as an accusation addressed to you is itself has a clear historical line, and it is not pretty. That individual should apologize, but probably won't.
